I need a specific command line tool and I have made a C program in my Linux shell. I have compiled the program with an ARM cross-compiler. I have then moved the program into the Android file system and tried to run it.
The output is permission denied.
What do I have to do, in order to run my own compiled programs in Android file system?

Opening CMD app on Android
I have got a software that I use on my pc, it is some kind of console that runs on CMD. Can I port or open the software in my phone? The file extension in the software is .exe but once I open it it opens Command Prompt, so I believe its a CMD app. Can Terminal Emulator open it? If so how do I do it?

Limiting Display Frame Rate to Lower
Is in Android there is an available database set for limits display frame rate? If they’re available, is using ADB/Root (Terminal), or how, or even it can't?

Is in Android there is an available database set for limits display frame rate? If they’re available, is using ADB/Root (Terminal), or how, or even it can't?
I've been searching this for years, and not get an answer yet. Actually, this is for tweaking to trigger any benefits. This like my other phone embedded feature is Xperia STAMINA mode which is it can set the display frame rate (to 2x lower from 30 fps) for battery saving. But... I mean is not only for that. Many others too that can benefit. So, is this can available on a pure Android system? Or this only self-made for manufacture's hardware so that not possible available on others except Xperia devices?
If there are other threads that I don't know. Please let me know. I'll understand it, and try if it makes sense.

In Linux, I like to launch the applications from the terminal. Most of the time it is the fastest way to launch apps, especially on repeated use.
In Android, there are good launchers like **FAST App Search Tool** that will do the job well. But I am still interested in launching apps from the terminal. For that, I installed *JS Terminal*, but I can't see any app names. Even pressing *Ctrl + T* doesn't show any app name.

How can I change the Home Screen wallpaper via ADB?
I know this question has been asked before, but none of the answers I read provided a way to instruct the phone to set only the Home Screen wallpaper. The Lock Screen wallpaper should remain unchanged.
For example, the following command works fine, but immediately after I send it to my Xiaomi phone, I get a popup window asking me which wallpaper to change: Home Screen, Lock Screen, or both.
~~~
adb shell am start \
-a android.intent.action.ATTACH_DATA \
-c android.intent.category.DEFAULT \
-d file:///path/to/my/image/on/device.jpg \
-t 'image/*' \
-e mimeType 'image/*'
~~~
I'm looking for a way to change the Home Screen wallpaper automatically, without any manual intervention.

The power button on my Android phone is dodgy and doesn't always work. I think it's on its last legs so I want to avoid pressing it if possible to extend its lifespan!
I know nothing about coding or how Android works. But I was wondering if it is possible to send the button press event to the system using this sort of code somehow: KeyEvent#KEYCODE_POWER .
Is there a way I can open the power menu via the screen only? Is there something I can type into a terminal (how do you get a terminal in Android?) that would open the power menu?

I got the inspiration here . It looks like AFWall+ is able to create a NAT forwarding policy to keep all traffic going through a SOCKS5 proxy and fool Google apps into thinking they are not connected via a VPN (Google apps implement additional security measures when connecting via
VPNService and if you are in China you will not pass the security check - the security check requests don't go through VPN, so they will EOF because GFW will kill these requests, read more here ).
So my question is, if let's say I have a socks5 server running at 192.168.1.1:1088 which tunnels all connections via vmess protocol (aka V2Ray) to remote servers in the US, how do I create my custom script? I have tried:
IP6TABLES=/system/bin/ip6tables
IPTABLES=/system/bin/iptables
ULIMIT=/system/bin/ulimit
PORT=1088
SERVER=192.168.1.1
$ULIMIT -n 4096
$IP6TABLES -F
$IP6TABLES -A INPUT -j DROP
$IP6TABLES -A OUTPUT -j DROP
$IPTABLES -t nat -F OUTPUT
$IPTABLES -t nat -A OUTPUT -o lo -j RETURN
$IPTABLES -t nat -A OUTPUT -d 127.0.0.1 -j RETURN
$IPTABLES -t nat -A OUTPUT -p tcp --dport 53 -j DNAT --to-destination $SERVER:$PORT
$IPTABLES -t nat -A OUTPUT -p udp --dport 53 -j DNAT --to-destination $SERVER:$PORT
$IPTABLES -t nat -A OUTPUT -p tcp -j DNAT --to-destination $SERVER:$PORT
$IPTABLES -t nat -A OUTPUT -p udp -j DNAT --to-destination $SERVER:$PORT

Using Terminal Emulator for Android , is there a way to enable a persistent command history?
So far, I've tried the following:
* Initial command of
export HISTFILE=$HOME/.mksh_history
* User mksh profile */data/data/jackpal.androidterm/app_HOME/.mkshrc* containing export HISTFILE=$HOME/.mksh_history
* System mksh profile */system/etc/mkshrc* containing export HISTFILE=/data/data/jackpal.androidterm/app_HOME/.mksh_history (though preferably the solution does not involve writing to */system*)
I'm able to get other Android shells (ash and bash) to write histories into *app_HOME* without issue. I'm also able to get mksh to write *HISTFILE* on Linux without issue.

I have a VPN configured on my android device running Lineage OS 18.1 (Android 11). I'm not using any third party apps, I'm simply using the standard Android settings to specify my VPN login data etc.
Now I'm looking for a simple way to enable7disable the VPN connection form the terminal without disruption.
I found a hacky way to do it by launching the VPN settings activity and then sending a bunch of key events to click on the connect/disconnect button.
Connect:
am start -a android.intent.action.MAIN -n com.android.settings/.Settings\$VpnSettingsActivity && input keyevent 20 && input keyevent 23 && input keyevent 61 && input keyevent 61 && input keyevent 61 && input keyevent 61 && input keyevent 61 && input keyevent 61 && input keyevent 66am start -a android.intent.action.MAIN -n com.android.settings/.Settings\$VpnSettingsActivity && input keyevent 20 && input keyevent 23 && input keyevent 61 && input keyevent 66

I have a Sprint LG G3 running Android 4.4.2. I'm using [Android Terminal Emulator](https://github.com/jackpal/Android-Terminal-Emulator/wiki) by Jackpal. It respawns after I close the app. I see the terminal process and the child shell but killing that way seems too manual.
When I closed the only window from the dropdown list at the top, it closes temporarily, then reappears in the "Recent apps" list. There is an un-swipeable notification that says "Terminal session is running". When I tap on either the thumbnail or notification, the "Window 1" comes back.
The only workaround I've found is rebooting.
Any better ideas to really close this app?

Using Termux to Backup Android's Contact List
In Termux's website's main page, they write (among other stuff): >"use rsync to store backups of your contact list on a remote server" This makes me wonder: Android's Contact List is stored in an SQLite DB, which is a file on the phone's internal storage. rsync synchronizes files.

In Termux's website's main page, they write (among other stuff):
>"use rsync to store backups of your contact list on a remote server"
This makes me wonder:
Android's Contact List is stored in an SQLite DB, which is a file on the phone's internal storage.
rsync synchronizes files.
So If I understand the required implementation behind this idea,
then what they mean by the quoted sentence, is that you can simply synchronize the whole SQLite DB file, to a remote server.
The problem is:
What happens when the day comes, and you need to **Restore** your Contacts DB?
I assume that Android will not let you copy the SQLite DB file that you saved aside, over the current (new, and empty) Contact List's SQLite DB file,
So how will we do the restoration?
I hope someone understood their idea in this sentence..
